When [[Harry Manfredini]] began working on the musical score, the decision was made to only play music when the killer was actually present so as to not "manipulate the audience".<ref name="slash">{{cite web|url=http://www.slasherama.com/features/harry.HTML|archive-url=https://web.archive.org/web/20060511052302/http://www.slasherama.com/features/harry.HTML|archive-date=May 11, 2006|title=Slasherama interview with Harry Manfredini|work=Slasherama|access-date=October 28, 2007}}</ref> Manfredini pointed out the lack of music for certain scenes: "There's a scene where one of the girls ... is setting up the archery area ... One of the guys shoots an arrow into the target and just misses her. It's a huge scare, but if you notice, there's no music. That was a choice."<ref name="slash"/> Manfredini also noted that when something was going to happen, the music would cut off so that the audience would relax a bit, and the scare would be that much more effective.{{citation needed|date=June 2018}}

Because the killer, Mrs. Voorhees, appears onscreen only during the final scenes of the film, Manfredini had the job of creating a score that would represent the killer in her absence.<ref name="slash"/> Manfredini borrows from the 1975 film ''[[Jaws (film)|Jaws]]'', where the shark is likewise not seen for the majority of the film but the motif created by [[John Williams]] cued the audience to the shark's invisible menace.{{sfn|Bracke|2006|p=39}} [[Sean S. Cunningham]] sought a chorus, but the budget would not allow it. While listening to a [[Krzysztof Penderecki]] piece of music, which contained a chorus with "striking pronunciations", Manfredini was inspired to recreate a similar sound. He came up with the sound "ki ki ki, ma ma ma" from the final reel when Mrs. Voorhees arrives and is reciting "Kill her, mommy!" The "ki" comes from "kill", and the "ma" from "mommy". To achieve the unique sound he wanted for the film, Manfredini spoke the two words "harshly, distinctly and rhythmically into a microphone" and ran them into an echo reverberation machine.<ref name="slash"/> Manfredini finished the original score after a couple of weeks, and then recorded the score in a friend's basement.{{sfn|Bracke|2006|p=39}} Victor Miller and assistant editor Jay Keuper have commented on how memorable the music is, with Keuper describing it as "iconographic". Manfredini says, "Everybody thinks it's cha, cha, cha. I'm like, 'Cha, cha, cha? What are you talking about?'"<ref name="ReturntoCrystalLake">{{cite video |last1=Miller |first1=Victor |last2=Keuper |first2=Jay |last3=Manfredini |first3=Harry |author-link3=Harry Manfredini |title="Return to Crystal Lake: Making of Friday the 13th" ''Friday the 13th'' DVD |medium=DVD – region 2 |location=United States |publisher=[[Warner Bros.]] |date=1980}}</ref>
